OS20.03 - Public Self-Reporting of Immunization Histories Using a Web Application (ID 134)
Brian Vanoosten, Ideaworks MEDIC, Mohawk College; Hamilton/CA
- Abstract
Purpose/Objectives: To evaluate the efficacy, usability, and accuracy of public reporting of immunization histories using a web application.
Methodology/Approach: A mixed methods approach including qualitative and quantitative evaluation tools including: · Repeated longitudinal usability studies during the development of the web application have been completed using a sampling of members of the target demographic (parents of school-aged children) using scripted use-case scenarios. · Pre and post exposure questionnaires administered to the same population sample to capture technical competency, vaccine attitudes, and impressions of the web application prototypes. · Quantitative evaluation of accuracy and completeness of submitted data from the public using synthetic personal health information from the usability scenarios. · Semi-structured interviews with different stakeholder groups including public health personnel, primary care clinicians, and parents of school-aged children.
Finding/Results: While final results are still pending, preliminary results from the ongoing usability studies indicate that many members of the target demographic are willing and able to accurately and completely report immunization histories for themselves and their school-aged dependents. Continuous testing of successive iterations of the web application have produced evidence of stepwise improvements to user satisfaction and quality of captured data. Qualitative feedback indicates a strong interest in the target demographic in such a tool and a high intent-to-use has been shown. Preliminary evaluations of submitted data show reasons for concern as some users have demonstrated difficulty interpreting and accurately transcribing technical-medical information such as immunization agents. Indicators show evidence that continuous improvement of the user interface has resulted in improved user comprehension and improved quality of captured data has followed.
Conclusion/Implication/Recommendations: The web application evaluated here shows promise to meet its objectives of providing a simple and structured tool for parents to submit immunization histories. An ongoing challenge for this project is the iterative improvements to the user interface that will help guide users to enter accurate and complete immunization histories and thus minimize administrative overhead by public health personnel who must vet submitted data before submission to the provincial database.
140 Character Summary: Can the public accurately report immunization histories using the web? We evaluate a new web application that has been developed to facilitate this in Ontario.
